UNETED STA HERMAN SCHLAICH, or hone Isiah]; cifrr, NEW Yo-RK.

To all whom it may concern;

Be it known that I, HERMAN' SCHLAICH, a citizen of "the United "States, residing in Long Island City, county of Queens, and

6 State of New York, have invented certain ing, willradiate light 'in both forwardand \r'earward directions and will makeiit uhneces'sary to leaveilluminated either the head-lights or the 'ta il-light of thesvehicle.

The general object of the present invention is'to provide-a lightwhich will sat-isfactorily serveboth as 'afspot-light and as a parking-light for vehiclesv In attainihg this objectyl have providcd'a light adapted to be supported for universalmovement'and provided with a casing having 'a' translucent portion through which thespot-beam is projected, and other translucent portions-for emitting lightfor parking purposes-indirections at substantially right angles'tothe direction of the s'pdt-beam. Inthis light,

I prefer to use a high-and-low'candle power lamp, such as adouble' filament lamp. :In addition, I-may -provide the light with a movable shutter which may be used to close the translucent portions ofthe casing through which lightis emitted for parking purposes. The invention will be understood from the following description, taken in' connectio'n with the accompanying drawing, in which Figure 1 is a plan view of a-combined'spotand parking light embodying the i'nvent1on; Figure 2 is an elevation thereof, partly in section: Figure -3.is an elevation, partly-in section, of. the light shownin Figures'l and 2, provided with a shutter for the translucent port-ions through which light' is emitted for parking purposes; Figure 4 shows an automobile'with the combined spot and arking light of Figures 1 and 2 mountedt'l iereon and arranged in; parking posi- Application filed November 8, 19 21.

which is mounted on ahollow arm 6 at- :tach'ed to any suitable and} we'll knowiiffoim "of f bracket adapted toZ be attazihefd to the wind-shield frame or a motor drive n' vehicle,'"the* -light being 'suppofrteddorj'uni- One form'ofsuch mou'ntversal movement. mg i's'shown m -F 1gure-8 and rsfherma-fter deseribe'd in COn'nec'tion with that {for-m Q of the invention illustrated in Fi ures," 5, 6 I fcas'ing'o is'a lamp 7,1preferably of the doublefilament variety, whichreceives current through wires 8 under the control of a switch at any (convenient location. Mounted within -the casi-ng behind the lamp 7 is a reflector 10 adapted to; project a concentrated beam or "s" (it-beam of light. The casing I v 5 is prov1 ed' with a translucent end which any suitable manner as by a ring; a turned'in edge 14 which engages the outside of-the' edge of'the crystal 12 and holds the inside of the edge of the crystal tightly 'zagai-nst a boss l5j0n the inside of the easing 5. The ring -l3- may also 'serve as a frame for holding a strip of translucent anaterial 16, such-as sheet celluloid, in posi- 'tion 'over' registering openings int-he cylindrical side of the casing 5 andin the ring:l3,as shown in Figure 2. The transparent *ma'ter'ial 16 is preferably white throughout that portion which covers the openings in the upper part of the casing,

may concasing in 13- having and is red throughout that'portion which Icovers the openings-in thelower'pa-rt of the teasing, for reasons hereinafterjexpl-ained. The inner edge of -'the ring 13 makes's'nug engagement with the outsidepf the casing 5, and thus holds the parts in their assembledzp sitions. a Thelight shown-"in Figure 3 is the same as the-light shown in Figures 1 and 2',ex'- ccpt that a shutter is'provided for covering the translucent portions of the casing through which light is emitted for parking 4 igure 4 shows the purposes. As shown, the ring. 13 which dslin'.fi s e l he y taL-Bran h's riP 16 of translucent material, is provided with channeled lugs 19 adapted to hold a shutter 20 which maymonsist of a band "ofsheet metal provided with oneroixmore outwardly extending knobs 21. The shutter 20 is pro vided with openings adapted to; register with the openings in the casing 5 and in the ring ,13. When all of the said openingsare in register, light .is. permitted to 1 emerge through them for parking. purposes; and when the light is not being used for parking purposes the shutter'20, by means of the knob 21, may be :moved-through substantially until the apertures in theshutter are out of register with the apertures in the ring 13 inthe casing 5, thereby preventing light from emerging througlr the cylindrical portion-of the casing 5.

If desired, the back of-the-casing ,5 may be provided with a -mirror 23 which, when .the light casing properly adjustedon its supporting bracket will enable thefo'perator to observe what is 'firPPIOfl-ChlillZ tflOIIlfbG' hind the vehicle.

I form of invention shown in-Eigures 1 and -2cmountedion-an .-automobile'andadjusted so as to serve as a parking light. lFrom this figure, "it will .be noted that the light notlonlyn-emit's white rays in a forward and red rays in a rearward direction, therebyproviding a warning to vehicles Y approaching both from the front and-from the rear of the vehicle; but also ,sheds light downwardly upon'the side of the vehicle, thereby making thelatter clearly visible when closely approached.

In Figures 5, 6 and 7 is illustrated'another embodimentof the invention which has .certain features of construction which are particularlyadvantageous, In this light, thecasing 25 may be of the simple form shown and may be-provided at its rear end with a flange 26 adapted to receive a convex ,mirror 27 which may be retained withinthe flange in any suitable manner as by a. ring 28.xWithin the casing 25 is a reflector 30, of the form shown, which-at its center is provided with a-flange 31 adapt- .edto receivea lamp socket32which may be retained within said flange by'means'of a set screw 33. As shown, the lamp socket 32 is of the bayonet ;-type; an'da lamp 35 of the double filament variety isshown inserted in said lamp socket. The rear of the lamp socket32 is shown as provided withterminals 37 to which are secured conductors 38 which may be led-outithro'ugh the hollow bracket arm 40; upon which the casing 25 is rotatably supported through the mediuiii of a flange 42, secured to said casing, anda nut 43 threaded on. the inne'rendof bracketarm and adapted .to cooperate with the-inside of the flange 42. A'Sbest shown in Fig- ;linedwith throughout the lower half of its annular ure 8,.the bracket arm 40 is provided at its outer ndwitlra collar'40 adapted to cooperate with the bracket 40, in a cavity 40 of which said collar is held by a nut 40 "The bracket 40 is preferably adapted to cooperatewiththeswind shield frame 40 of the vehicle, to which it is secured by the bolts 40 which passvthru the bracket 40 and a clamping plate 40 between which the frame 40 is gripped. By the construction just described, the lamp casing 25 is supported in-a manner which permits its universal movement on the vehicle,-as is cuswill, .of course be understood that this particular construction .of lamp mounting forms no part of the present invention, and that it may be modified in many respects without departing from the spirit thereof.

At its outer edge, the reflector 30 is preferably= formed into a flange 45, the outer diameter of which is about the same as the outer diameter. of the casing 25 at its open end. The light is provided with a crystal 146 which is preferably pan-shaped or provided with an annular-portion out of the plane of the mainportion 'as shown, and is provided with a flanged edge conforming in. shape-to the edgeofthe reflector 30. -Adapted to cooperate with the'edge of the crystal-46, is a retaining ring 47 which may lie-secured to the casing-25 in any suitable -manner, asby means of a pin 48 and ascrew 49. The ring 47' is provided with an outer in-turned edge" which engages the outside of the edge of the crystal 46; and the ring 47 may be of sheet metal. -Between the back of the reflector 30 and the disk 52 is interposed a coiled'spring 53 which is adapted to force the reflector 30 toward the crystal 46 and the latter into engagement with the flangededge of the ring 47. The crystal 46 is-thus held in a manner which prevents rattling; and a. dust tight joint between the crystal 46 and the reflector 30 is provided. The crystal 46 is preferably painted red, or red translucent material,

portion,.-as.shown at56.

It will be obvious that. with the'form of .theinventionshown in Figures 5,'6 and'7, light is emitted both axially and radially through the crystal: and that when the spot beam is directed downwardly for parking purposes,-the rays which are emitted in 'a forward direction through the edge of the crystal will be white-,whereas those emitted rearwardly will be red. In this embodi-' inentof the invention, therefore, the edge tomary in connection with spotlights. It

portion of the crystal may be regarded as part of the casing; and the device serves the same purpose as the embodiment shown in Figures 1,. 2, and 4.

In all of the embodiments of the invention herein described, a two filament lamp is preferably employed in order that, when the lightis used for parking purposes, cur-.

rent consumption may be reduced to a minimum by the use of the low candle power filament, while the high candle power filament furnishes the light for the powerful spot beam. It will be obvious, however, that two lamps, one of high and one of low candle power may be used; and that a single filament lamp may be employed, and current consumption reduced when the light is used for parking purposes by inserting in series with the lamp a suitable reistance.

In addition to serving as a combined spot and parking light, any of the 'lights herein described may also be usedfor illuminating the temperature indicating instrument which is usually mounted upon the radiator cap of a motor driven vehicle. The light can be so used conveniently, when it is not being employed either as a spot light or as a parking light; and when so used, the rays from the low candle power filament, projected as a spot beam, Will be sufiicient to illuminate the temperature indicating instrument without projecting a dazzling beam in a forward direction, which would be course be objectionable.

while I have shown preferred forms in which the invention may be embodied, it is to be understood that these forms are merely illustrative and that the inventionmay be embodied in other forms without departing from the spirit as defined in the appended claim.

What I claim is:

In combination with a motor vehicle, a combined spot and parking light mounted for universal movement on toe left side of said vehicle and comprising a casing, a lamp and reflector therein, a translucent portion in said casing through which the spot beam of light is projected, and translucent portions in said casing so located that light will shine throughsaid translucent portions toward the front and rear of the vehicle when the spot beam is directed downwardly.

In testimony whereof I have alfixed my signature to this specification.

HERMAN SGHLAICH.
